ECHEMI Editorial Reference

Avobenzone is an oil soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays and a dibenzoylmethane derivative.Target: OthersAvobenzone is an oil soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays and a dibenzoylmethane derivative. It can degrade faster in light in combination with mineral UV absorbers like zinc oxide and titanium dioxide, though with the right coating of the mineral particles this reaction can be reduced.
Avobenzone is a member of dihydrochalcones.|Avobenzone is dibenzoyl methane derivative. It is oil soluble ingredient. Avobenzone has the ability to absorb ultraviolet light over wider range of wavelengths. It is included in many commercially available sunscreens which are used as wide spectrum sunscreens. Avobenzone is very sensitive to light, to increase its stability and duration of action, photostablizers are added in the sunscreen product. Avobenzone has an absorption maximum of 357 nm. Sunscreens containing avobenzone is indicated for providing protection from the sun. In addition to limiting the skin's exposure to the sun, using sunscreen agents may help reduce long-term sun damage such as premature aging of the skin and skin cancer.|Avobenzone is a sunscreen blocker. Avobenzone is a topical, broad range UV protector and blocks UVA I, UVA II, and UVB wavelengths, thereby limiting the impact of UV rays on skin. (NCI05)
